    I applied for technical student position. After initial submit I was contacted after 1-2 months. I got only 2 phone interviews with very friendly guy. He was curious about my skills and work experience I did during my university. The whole phone call was not longer than 30 min. The guy described me the work I should do and we checked once more the start date.

    First, you have to fill out a very long application with many questions on competencies etc. then assuming HR like what they see, you get invited to a video interview which you can do in your own time.

    Firefighter Interview

    Anonymous Interview Candidate in Geneva (Switzerland)
    No Offer
    Positive Experience
    Difficult Interview

    Application

    I applied online. I interviewed at CERN (Geneva (Switzerland)) in May 2017.

    Interview

    The interview process was such a great experience.
    All the candidates were treated equally and the atmosphere between us was very friendly. We encouraged each other. It was very well organised. They make you feel comfortable but they require high-level candidates at the same time. Therefore, there is no time to get relax.

    Interview Questions

    • There were 50 minutes of questions. Most were about my experience but others were a little bit tricky. A question I will never forget was; "Mention something your organisation have imposed and you have complained". That was a difficult one.   Answer Question

    Technology Analyst Interview

    Neutral Experience
    Difficult Interview

    Application

    I applied online. I interviewed at CERN (Geneva (Switzerland)).

    Interview

    The interview lasts most of the day and they fly you out to Geneva for it. It is composed of a panel interview (my panel had 5 people including direct supervisor, technical expert, group & department heads and HR rep). You also have to give a presentation based on a topic given to you in advance. After this, I had a technical competence test (case study based on the type of work the role involved). I then went to lunch with the other candidates and recruiters before finishing the day with a series of smaller interviews with existing members of the team. Which order these elements occurs in just depends on how many other candidates are in your selection board and HR's scheduling - you may start with the test or with another element.

    Java and Database Developer Interview

    Positive Experience
    Average Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at CERN (Geneva (Switzerland)) in March 2017.

    Interview

    * online test
    * video interview (recording your answers of written questions, bit weird but practical I guess)
    * on place interview - it was whole day, rather exhausting, but overall interesting experience. Take a watch with you since in my room there was no clock and during the case study written test, you are not allowed to have a phone with you. What I found redundant is the apart of the case study questions, there were other small things that they could have included in the online test.

    Interview Questions

    • To write more advanced SQL DB statement, for which you have to train well your SQL knowledge (don't rely only on your daily work - it won't be sufficient). There was a task to implement data structure in Java (from what I remember was BlockingQueue), for which I didn't have the time and a bunch of small other easy java related questions.   Answer Question
